A Comprehensive Guide to Biofloc Fish Farming in India 2024

Beginners looking for a sustainable and financially feasible strategy will find Biofloc fish farming to be especially interesting as it has become an innovative and environmentally beneficial technology in the field of aquaculture. This thorough manual explores the principles, advantages, detailed procedures, Government Subsidy, and even factors to take into account while choosing training facilities in India.

Understanding the Principle of Biofloc Fish Farming:

In traditional fish farming, the accumulation of waste from food, feces, and urine poses a significant challenge to water quality. Elevated levels of ammonia, nitrite, and nitrate can lead to various health issues in fish. Here enters Biofloc fish culture, introducing a natural ecosystem that converts ammonia into nitrite and then into nitrate. Finally, bacteria transform nitrate into gaseous nitrogen, enhancing water quality. This process, in conjunction with phytoplankton and zooplankton, not only maintains water quality but also provides additional nutritional value to the aquaculture system.

In simpler terms, Biofloc fish farming minimizes the waste of fish food in ponds, converting fish waste and leftover food into bacterial protein that is edible for the fish. This innovative system reduces the need for water changes, making it a more sustainable and efficient method compared to traditional farming.

The Benefits of Biofloc Fish Farming in India:

  1. Profitability: Biofloc fish farming proves to be more profitable than traditional methods.
  2. Ammonia Reduction: The system naturally reduces ammonia levels, creating a healthier environment for fish.
  3. Natural Food Source: Fish receive natural and nutritious food, enhancing their overall well-being.
  4. High Protein Diet: Fish in Biofloc systems experience enhanced protein intake, promoting growth.
  5. Exceptional Growth Rates: Biofloc fish farming often leads to remarkable growth in fish.
  6. Disease Resistance: The occurrence of diseases is minimal, accounting for less than 1% of fish.
  7. Excellent Water Quality: The system maintains consistently good water quality, a significantfactor in successful aquaculture.

Building the Biofloc Fish Farming Infrastructure:

Constructing an efficient Biofloc fish farm involves several essential steps. The tank must be designed with a slope from all sides towards central drainage to facilitate water removal. A 15 cm down pipe ensures effective drainage without blockages. A 4-diameter tank with a water level of 1M, leaving 0.2 tank empty, is recommended. Incorporating eight oxygen pipes into the tank ensures proper aeration, a key factor in maintaining water quality.

Water Treatment Protocols for Success:

In Biofloc fish farming, water treatment is critical. The two most important ingredients in water treatment are probiotics and molasses. Black jaggery is used to make molasses, which is boiled and combined with water to create a liquid. 10 milliliters (ML) of molasses are added to a 1000-liter tank; for a 10,000-liter tank, the amount is increased to 100 ML. Market-available probiotics are added at a rate of 5 milliliters per 1000 liters, increasing to 50 milliliters for a tank holding 10,000 liters. These elements are essential for promoting bacterial development and preserving the purity of the water.

Key Considerations in Biofloc Fish Farming:

  • Tank Preparation: Clean the tank thoroughly with soap and sun-dry it for a day before initiating the Biofloc system.
  • Water Aeration: Apply aeration from an air pump with an air stone for two days to ensure proper oxygenation.
  • TDS Measurement: After two days, check the Total Dissolved Solids (TDS) with a tool, aiming for a minimum value of 1800 and not exceeding 2000.
  • pH Level Management: Keep the pH level between 6-8, adjusting with slaked lime or dolomite if necessary.

Choosing Fish Seeds and Introducing Them to the Tank:

Selecting healthy and compatible fish seeds is important for the success of a Biofloc fish farm. Characteristics such as completeness, cleanliness, and playfulness are indicators of robust fish. Acclimate the fish to the tank environment gradually, withholding food for the first day and introducing it after 12 hours.

Feed Management for Optimal Growth:

In Biofloc fish farming, the kind of food that is fed to the fish is important. Food that is swimmable keeps it from sinking to the bottom and generating ammonia, which is poisonous to fish. Fish size should be taken into account when adjusting protein intake; smaller fish initially need a higher protein content. Three to five percent of the fish’s weight should be fed.

Water Management for Sustainable Practices:

Sustaining water quality is essential to the profitability of fish farming with Biofloc. An important factor is the carbon/nitrogen (C/N) ratio, which should ideally be kept at 20–40% floc. Probiotics and molasses modifications are required if floc levels fluctuate. In addition, the system may need to replace the water if it detects a bad odor or low water quality.

Harvesting and Medication Protocols:

Harvesting in the afternoon or evening is recommended, with a 12-hour fasting period before harvest. Slow water drainage during harvest preparation ensures the well-being of the fish. In case of illnesses, antibiotics or natural remedies like ground papaya leaves can be employed. Medication dosage should be carefully administered based on the severity of the condition.

Ensuring Healthy Fish Cubs and Biomass Management:

The health of fish seeds is critical for the success of a Biofloc fish farm. Adequate biomass is essential for feeding fish, and calculations based on weight ensure optimal food distribution. Special attention is required for weak or sick fish, with the incorporation of vitamins and antibiotics into their diet.

Calculation of Ammonia Levels and Biofloc Fish Farming Guide:

Understanding the ammonia levels in the water is vital for maintaining a healthy Biofloc system. Ammonia testing kits help determine the concentration, and calculations involving molasses and carbon are used to control ammonia effectively. The C/N ratio plays a important role in the conversion of ammonia to protein, highlighting the core purpose of Biofloc fish farming.

Guidance on Making FCO (Floc Carbon Oxygen) in Biofloc Fish Farming:

FCO is a vital component in the digestion of fish food and contributes to ammonia control. The guide provides two methods for preparing FCO, emphasizing the importance of its application in enhancing the efficiency of the Biofloc system.
